Thread: Buffering Issues

  1. #1

    Angry Buffering Issues

    I have 690 Movies, in an .avi format, on a External Hard drive and I stream them through my PC and WiFi to my Xbox. I stream viewing over my wifi for hours on end. I have no buffering when I stream, Comcast, Vudu or Netflix and I do that a single hiccup. However, when I stream any of my .avi movies it streams normal except when the movie is about 75% done and it starts to buffer for 30 seconds and proceeds. When I watch one of my high def .avi movies it buffers a lot. I understand there is more content and that is why the buffering.

    My wifi speed was just upgraded, to the fasted I could find, to support the full arrange of devices that I have on connected. But, still have the buffering issue no matter what I try. I have searched the forums many times and have not found anything that would solve this problem. Now, if this a PC issue, an Xbox issue (I have the same issue with my PS3) or a KooRaRoo Issue? If it is a KooRaRoo issue, can I increase the buffer space?

    Thanks,

    C

    Let's first check one of those files. Can you please right-click on one such AVI in KRR and post the output of the "File Information" command?

    Then, just so I understand your setup better: your external drive, is it attached via USB to the PC or is it a NAS? If the latter, is it wired or wireless? What is the network type that you are using - G/N?

    Are the devices (Xbox/PS3) connected wireless as well?

    Also, when such a file is streaming, can you please check KRR's Status pane and see if it's sent natively or being transcoded.

    KooRaRoo itself is unlikely to be the issue here (are you using the latest version?) - it can send out hundreds of megabytes of data per second and is only limited by your network bandwidth and your CPU power. I suspect that it's either the files or KRR is trying to transcode them or your network can't cope.

    very few wifi routers can stream 1080p successfully, a good router can do 720p, so i stick with 720.

    Angry The answers to all your questions.

    Question: Let's first check one of those files. Can you please right-click on one such AVI in KRR and post the output of the "File Information" command?

    Answer: Two file types. 720p and it plays 3/4 of the way through the movie and then start to buffer. It use to be one buffer bar and back to the movie. Ever since we switched to a fast wifi we get 7 or 8 buffer bars and/or we get out and resume the movie and it picks up where it left off and everything works.

    With the 1080i movies, they worked well with the old router; now I cannot even play a movie without it buffering every 3 or 4 minutes.

    For 720p AVI files here is the information you requested.

    Question: Then, just so I understand your setup better: your external drive,

    Answer: Yes

    Question: is it attached via USB

    Answer: Connected using a USB3 to the PC

    Question: or is it a NAS?

    Answer: Just USB

    Question: If the latter, is it wired or wireless?

    Answer: The network is wireless.

    Question: What is the network type that you are using - G/N?

    Answer: G most likely. I have a small appartment and the PS3 or Xbox is only 30 feet from the rounter. No problems with playing Netflix or connections to any of the other wireless devices.

    Question: Are the devices (Xbox/PS3) connected wireless as well?

    Answer: Both work fine with all applications.

    Question: Also, when such a file is streaming, can you please check KRR's Status pane and see if it's sent natively or being transcoded.

    Answer: Native, whe I transcode the sound will NOT work.

    Question: KooRaRoo itself is unlikely to be the issue here (are you using the latest version?)

    Answer: Unlikely, maybe. However, everything points to KRR.

    Question: it can send out hundreds of megabytes of data per second and is only limited by your network bandwidth and your CPU power. I suspect that it's either the files or KRR is trying to transcode them or your network can't cope.

    Answer: Still do not explain why the router worked before and does not know.

    Old Router was a LINKSYS WRT54GS2 V1 (about 3 years old)

    New one is a TECHNICOLOR tc8305c.

    If it is not KRR; is their a system setting I can change? Any help is needed and if I cannot solve this. I look for another answer other than KRR.

    My old router did and it worked without a glitch. Something is causing this buffering. It was a small issue before; however, now it is a bigger issue.

    Thank you for the file information.

    The next step is to confirm that all settings are correct and I need to see logs for that.

    Please enable logging by ticking the Enable Logging item under the Tools menu. After that restart the server using the stop/start button on the toolbar. Then try streaming one of the files for which you sent me file information above. Once it begins to buffer, stop the server and send in the logs to support (at) kooraroo (dot) com. To find the logs, please go to Tools -> Options -> File Locations and click the Open button on the Logs folder.

    With regards the router settings - please check that UPnP is turned off on the router and also there is no QoS either.

    Angry KRR Log

    I hope the log get attached/

    Thank you for the logs.

    I'm not seeing anything unusual in there - seems to be streaming just fine.

    Do you still have your old router that you could test with?

    Also, is it an option to run a cable connection from the router to the Xbox for testing?

    Basically, I'd like to confirm that it's not the file itself, but rather something else.

  9. #9
    Both the old router and a wired connect requires KRR to buffer.

  10. #10
    Ok, thank you for testing. So that means it's not a connection issue and this leaves us a couple of possibilities:

    1) It's the file itself. The encoding of the file may be such that this causes an issue in playback. One way to test this is to copy it on a USB stick and play it directly off the Xbox.
    2) We can try another file description for it to see if that helps. Please open a ticket through http://support.kooraroo.com and I'll send you an updated device profile to try this.
